FALLBROOK  Four people escaped a raging fire that destroyed their Fallbrook home Sunday night.

When firefighters arrived at the house on Palomar Drive off Via Monserate about 7:30 p.m., the structure was totally involved in flames, said North County Fire Protection District spokesman John Buchanan.

It took about an hour to put out the blaze, Buchanan said. He said firefighters kept the flames from spreading to a home next door.

The cause of the fire is under investigation. Buchanan said the home was a total loss, with damages to the house and contents estimated at $750,000.
